Broadstone.fl

Networks often contain 'forbidden links', where interactions are not possible
 between two taxa due to factors such as large differences in body size,
 spatio-temporal mismatches or specialised flower morphology in flower visitation
 networks. <code>Broadstone.fl</code> summarises the forbidden links in the
 <code>Broadstone</code> food web, estimated from the interactions observed
 from a complete year's sampling (Table 3 in Woodward et al. 2005). This
 table is illustrative, and should not be considered a definitive list.

datasets

Null models to analyse ecological networks (e.g. food webs,
flower-visitation networks, seed-dispersal networks) and detect resource
preferences or non-random interactions among network nodes. Tools are
provided to run null models, test for and plot preferences, plot and
analyse bipartite networks, and export null model results in a form
compatible with other network analysis packages. The underlying null model
was developed by Agusti et al. (2003) Molecular Ecology
<doi:10.1046/j.1365-294X.2003.02014.x> and the full application to
ecological networks by Vaughan et al. (2018) econullnetr: an R package
using null models to analyse the structure of ecological networks and
identify resource selection. Methods in Ecology & Evolution,

Null Model Analysis for Ecological Networks

Broadstone.fl function

A data frame with 20 columns and seven rows, one row for each of the
 seven predator taxa. The first column (<code>Predator</code>) lists the seven taxa,
 whilst the remaining 19 columns are the invertebrate taxa in the food web:
 each element indicates whether the predator can consume that taxon (1) or
 whether the link is 'forbidden' (0).
